The Guide to
Coloured Stones

Our diamonds are brighter and more vibrant because we craft them that way. At Tiffany, nearly 1,500 of the world’s most talented artisans craft diamonds to the highest standards. Only the most expertly crafted diamonds earn the right to be placed in the legendary Tiffany Blue Box


The 4 Cs

Every diamond, like a human fingerprint, has certain distinguishing characteristics. The 4Cs—color, clarity, cut and carat weight—are the globally accepted standards for assessing the quality of a diamond. At Tiffany, we only accept 0.04% of the world’s gem-grade diamonds.



Cut is determined by how a diamond's

facets interact with light.



Clarity is a measure of the  qpurity and rarity of the stone.



Colour refers to the natural tint inherent in white diamonds.



Carat denotes the weight of a diamond.

Gemstone Traceability


We believe fine craftsmanship starts with a respect for our natural world, responsibly sourcing high-quality raw materials and continues through to the creation of the final piece of jewelry. From the moment they are unearthed, Tiffany diamonds selected for our engagement rings never leave the hands of highly skilled artisans, who work with passion and precision to unleash intense vibrancy and light. Once a rough diamond is deemed worthy of the Tiffany name, it is delivered to our diamond cutting experts and our master craftspeople. Tiffany is proud to employ nearly 1,500 expert cutters and polishers in our own state-of-the-art workshops to ensure our sourcing practices honor the places and people that provide us with such astonishing beauty. We go above and beyond the Kimberley Process—with our own chain of custody controls and by advocating for stronger global standards—to ensure that human rights and the environment are protected.
